-----Original Message----- From: Bob Cook >>>As a general rule – therefore it can be said that there is no correlation between loading ratio and heat unless it is related to isotopes, meaning that this detail about the lack of any correlation can be limited to hydrogen (protium) and does not necessarily apply to deuterium<<<
I do not agree. If the loading causes micro cracking in the Pd matrix, it very well may correlate with heat. Micro cracking would apply equally to H and D and thus would suggest that D is necessary for the NAE reaction to occur in Pd. Since the loading near the surface is significantly greater than away from the surface, the cracking near the surface could be expected to be more frequent with higher NAE density. Bob, Yes, micro cracking would apply equally. But your logical error is in assuming that cracking is necessary for gain. It isn't, depending of course on how it is defined. Cracking is one of many possible routes to gain and NOT the only route by far. At the nanoscale, it would be irrelevant anyway. In the Pd matrix for instance, cracking correlates to excess heat with deuterium, and NOT with hydrogen. In fact some of the SEM images of the Arata-type particles which give excess heat with nickel have no cracking per se, since they are essentially too small to crack. This material is active for hydrogen and has no cracking. I believe Brad Lowe may be sending some of his supply to Quantum Heat. http://www.quantumheat.org/images/NanoPowders/Quantum_Sphere_Nano_Nickel_SEM.jpg
